All elders equal. Bible only for doctrine (elder/bishop one office)
150 AD One elder exalted above the others (elder/bishop still one office) Bible still rules
200 AD One Bishop per church overseeing the eldership (elder/bishop two offices) Bible only
250 AD One diocesan Bishop overseeing other Bishops of other churches. Still bible only
300 AD One Metropolitan Bishop overseeing other diocesan Bishops (Creeds replace Bible)
381 AD One Patriarch overseeing Metropolitans (Man replaces Creeds)

Let's Restore Bible organization of the church!
